Topic: Possible Caithness ?

[keith]

Around 8 inches tall, polished rim and base, did wonder about Whitefriars but have been told it isn't

I'd have thought it's Murano sommerso, it appears to have to have quite a lot of wear so has some age,

Yes to Caithness. 
Domhnall OBroin, no.4022, designed c1961, in the colour Peat.
Highly successful. Produced for decades, named Stroma.
(straight out of Mark's Caithness book, p 21. I'm not wrong. )

The wfs ones are distinguishable from Caithness ones. The finishes are different, but I cannot for the life of me remember what the difference is.
Caithness have flat polished bases and polished rims. I can't lay my hands on one right now to check for bevelling on the rim, but I think there is.
(I've just checked your pics)
I can't remember how the wfs ones are finished.
Colour is always a good clue - both Caithness and Wfs are quite specific about those.
I think the wfs ones might have bulgier bottoms although Caithness did a shorter, wider and bulgier version too, it was designed by Charles Orr and is no. 4033. (p 27 of Mark's book)
They are quite different to wfs.
